23. Describe the slopes of perpendicular lines

Answers

Answer:

The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.

The slopes of perpendicular lines when multiplied together gives the product as -1.

What is the slope of straight line?

The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.

The negative slope indicates the rate of decrease while the positive shows the rate of increase.

Suppose the two perpendicular lines have equations as follows,

y = m₁x + c₁  and y = m₂x + c₂.

Suppose m₁ = tan θ

Then, m₂ = tan (90° + θ)

Apply the trigonometric identity to obtain,

m₂ = tan (90° + θ)  = -cot θ

Now, m₁ × m₂ = tan θ × -cot θ = -1

Thus, the products of slopes is -1.

Hence, the product of slopes of two perpendicular lines is -1.

Y=2x

Y=7x-20

I’ll give you brainlessly

Answers

Answer:

(4,8)

Step-by-step explanation:

y = 2x

y = 7x-20

Step 1: plug in 2x for y

Step 2: subtract 7x on both sides

Step 3: divide by -5 on both sides

Step 4: plug in 4 into y = 2x

2x = 7x -20

-7x      -7x

-5x  = -20

-5         -5

x = 4

What would be the best method to solve
the system of equations below?
6x + 3y = 21
2x – 3y = -13

Answers

I would change 6x+3y=21 to y=-2x+7.
You can isolate the y value by subtracting the x to the other side. All the numbers have 3 in common, so you need to divide all of them by 3. I would then substitute the new equation into the 2x-3y=-13, making it 2x-3(-2x+7)=-13
You wove the equation, and once you get your x value, you needles to substitute it in the equation: y=-2x+7
The final answers will be x=1 and y=5

Elimination method is the best method to solve the system of equations below

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given system of equations

6x + 3y = 21...(1)

2x – 3y = -13...(2)

Add equations (1) and (2)

6x+3y+2x-3y=21-13

8x=8

Divide both sides by 8

x=1

Now plug in x value in equation 1

6+3y=21

Subtract 6 from both sides

3y=15

Divide both sides by 3

y=5

By Elimination method we find the values of x and y.

Hence, Elimination method is the best method to solve the system of equations below

The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the number of tacos made. How does the total cost change for every taco special the food truck makes?
A. The total cost increases by $1.
B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.

Answers

Answer:

C. The total cost increases by $2.50

Step-by-step explanation:

This is because 1 dollar is constent--- you will always have 1 dollar.

However 2.5 is the change, you have to times a number to get the answer.

EX:

(t) = 2.5t + 1

(4) = 2.5( 4) + 1 ----- plug in 4 for t

= 10 +1

= 11

The is the multiplyer or change is the 2.5t

and when you graph it it will almost always be the slope of the line.

in the diagram the measure of angle one is 3X the measure of angle two is 12 X what is the measure of angle 4

Answers

Answer:

144°

Step-by-step explanation:

m<1 =3x

m< 2= 12x

1&2 are supplementary angles, so

3x+12x= 180

15x=180

x= 12°

measure of angle 4 equals the measure of angle 2

because they're head opposite angles

m<4= 144°
